Aurora J. ★★★★★ Oct 22, 2026

I was a little worried about dropping this into my 3.8, but it bolted right in with the included harness—quiet and strong from the first startup. The 420lph flow is way more than my stock pump could manage, and I can actually hear the difference under boost.

Riley ★★★★★ Oct 21, 2026

The install kit made swapping out my old pump in the Genesis Coupe pretty straightforward. I've got the 3.8 and the 420lph flow is exactly what I needed for my tune. Feels solid so far.

Owen ★★★★★ Oct 20, 2026

My old pump was starving the engine at higher boost, but this 420lph unit keeps the fuel pressure rock solid now. The included install kit made swapping it into my 2011 Genesis Coupe 2.0T way simpler than I expected.
